Description

콘크리트 도상용 RC침목{RC-tie of a concrete-ballast track}RC sleepers {RCC-tie of a concrete-ballast track}

본 발명은 콘크리트 도상용 RC침목에 관한 것으로, 특히 콘크리트 도상에 적합한 RC침목을 별도로 제작하고, 이 RC침목 내부에는 철도 차량운행시 가해지는 외부압력을 충분히 견딜수 있는 상,하부철근 및 앵글을 적절하게 배열 설치하므로서전체적으로 RC침목의 강도 및 내구성을 증대시켜 수명을 영구적으로 사용할 수 있도록 한 콘크리트 도상용 RC침목에 관한 것이다.The present invention relates to a concrete sleeper RC sleeper, in particular to make a separate RC sleeper suitable for concrete, the inside of the RC sleeper can adequately withstand the upper, lower reinforcing bars and angles that can sufficiently withstand the external pressure applied during the operation of the railway vehicle The present invention relates to a concrete sleeper RC sleeper that can be used permanently by increasing the strength and durability of the RC sleeper as a whole by installing the array.

일반적으로 도상(ballast)은 레일, 침목을 경유하여 전달된 하중을 넓게 분포시켜 노반에 전달하고, 온도변화에 의한 레일 신축으로 나타날수 있는 침목의 이동을 도상저향력으로 막아 방지하며 차량의 진동을 흡수하여 승차감을 좋게 할뿐 아니라 빗물배수를 용이하게 하고 잡초가 자라는 것을 막는등의 여러가지 역활을 수행하는 것으로 알려져 있다. 따라서 상기와 같은 특성을 잘 갖추고 있으면서 구하기 쉬운 자갈 또는 깬 자갈이 도상의 재료로 널리 사용됨에 따라 현 지하철 구간중 교량부분을 제외한 전구간이 자갈도상 궤도로 이루어져 있다.In general, the ballast distributes the load transmitted through the rail and the sleeper to the roadbed by wide distribution, and prevents the movement of the sleeper which may appear as the rail stretching due to the temperature change by the phase shifting force and absorbs the vibration of the vehicle. It is known to perform various roles such as improving ride comfort and facilitating rainwater drainage and preventing weeds from growing. Therefore, the gravel or crushed gravel, which is well equipped with the above characteristics and is easy to obtain, is widely used as a material for the phase, and all sections except the bridge portion of the current subway section are composed of gravel phase tracks.

상기와 같은 목적을 갖는 종래 자갈도상 궤도 구조를 간단하게 살펴보면 레일 하단에는 침목이 체결 고정되어 있고, 이 침목의 하단측에는 자갈도상이 깔려져 있다. 이와 같은 상태에서 차량이 운행할때 차량의 하중이 레일에 가해지면 자갈도상은 침목과 함께 하중을 노반으로 골고루 분산시키게 된다.Looking at the conventional gravel-shaped orbit structure having the purpose as described above, the sleeper is fastened and fixed to the lower end of the rail, the gravel-shaped is laid on the lower side of the sleeper. In this state, if the load of the vehicle is applied to the rail while the vehicle is running, the gravel phase distributes the load evenly to the roadbed with the sleepers.

이러한 종래 자갈도상을 이용하여 소기의 목적을 달성할 수 있다는 잇점은 있으나, 장기간 사용시 자갈이 깨져서 마멸되어 미립자화되고 토사유입으로 배수가 나빠질 수 있을뿐 아니라 이로인해 굳어지면 탄성을 상실하게 된다. 이때에는 자갈치기를 하거나 자갈을 바꾸어 주어야 하므로 많은 인력이 필요하게 되고, 작업을 한다하더라도 열차 횟수의 증가로 인해 작업 시간을 얻는데는 많은 어려움이 있었다.There is an advantage that can achieve the desired purpose by using such a conventional gravel bed, but when used for a long time, the gravel is broken and abraded into fine particles and drainage is bad due to soil inflow, as well as it loses its elasticity when it is hardened. At this time, gravel or gravel must be changed, so a lot of manpower is required, and even if you work, there was a lot of difficulty in getting time due to the increase in the number of trains.

또한, 자갈이 미립자화됨에 따라 마찰력과 충격흡수등 도상기능이 현저하게저하되므로 그만큼 열차운행의 안전성을 확보하기 어려울뿐 아니라 승차감이 저하되었으며, 미립자화된 자갈에 의해 분진이 발생되어 지하 환경이 취약하는 등의 제반 문제점이 발생되었다.In addition, as the gravel becomes granular, the drawing functions such as friction and shock absorption are significantly reduced, which makes it difficult to secure the safety of train operation, and the ride comfort is reduced. Various problems have arisen.

최근에는 상기와 같은 자갈도상 문제점을 감안한 콘크리트 도상이 안출되어 현재에는 전 궤도 구간이 자갈 도상에서 콘크리트 도상으로 교체되고 있는 현실정이며, 이에 따라 콘크리트 도상에 적합한 RC침목이 요구되고 있는 현실정이다.In recent years, the concrete bed is conceived in consideration of the above problems of gravel drawing, and now, the entire track section is replaced with the concrete bed from the gravel bed, and accordingly, the RC bed suitable for the concrete bed is required.

따라서 본 발명의 목적은 상기와 같은 종래의 문제점을 감안하여 안출한 것으로, 콘크리트 도상에 적합한 RC침목을 제공하여 효과적으로 도상 역활을 수행할 수 있도록 한 콘크리트 도상용 RC침목을 제공하는데 있다.Therefore, an object of the present invention has been made in view of the above-described conventional problems, to provide a concrete sleeper RC sleeper to provide an effective RC sleeper by providing a suitable RC sleeper on the concrete.

본 발명의 다른 목적은 RC침목 내부에 철도 차량운행시 가해지는 외부압력을 충분히 견딜수 있는 상,하부철근 및 앵글을 적절하게 배열 설치하므로서 전체적으로 RC침목의 강도 및 내구성을 증대시켜 수명을 영구적으로 사용할 수 있도록 한 콘크리트 도상용 RC침목을 제공하는데 있다.Another object of the present invention is to increase the strength and durability of the overall RC sleepers by permanently installing the upper, lower reinforcing bars and angles that can adequately withstand the external pressure applied to the railroad car running inside the RC sleepers can be used permanently life To provide a concrete bedding RC sleeper.
